Hex Socket Bolt

Hex socket bolts are also known as hex socket machine screws and they require a hexagonal or special-shaped wrench for fastening. These bolts have six load-bearing surfaces which provide greater resistance against twisting compared to flat bolts. Hex socket bolts are perfect for use in narrow and cramped spaces where external hexagon bolts cannot be used. When fitted in the workpiece, the entire bolt must be sunk in order to ensure a smooth and aesthetically pleasing finish while also making future maintenance easier and the performance more reliable.

These bolts find application across a wide range of machine tools and their accessories, making them the most commonly used fasteners in this domain.

Countersunk head hex socket bolt

The machine screw with a hex socket head is commonly referred to as a Countersunk head allen bolt. It offers a strong connection with easy disassembly, and it doesn't slip easily. However, one needs to use a hexagonal wrench to install or remove it. This type of screw is widely used in areas where mechanical parts' surface cannot have protrusions.

Pan head hex socket bolt

Pan head hex socket bolts, also known as pan head hex socket head machine screws, boast a larger compression surface compared to cylindrical head and countersunk head machine screws. This results in a greater connection contact area, requiring the use of matching screws for installation and disassembly. The tool of choice for tightening and loosening these bolts is an Allen wrench. These fasteners are typically utilized for securing aluminum profiles.

Hex socket shoulder screw (plug screw)

Shoulder screws, also known as plug screws, stop screws, stop bolts, brake bolts, and more, are essential components used in combination with bolt pull rods. These screws play a crucial role in controlling the fixed mold seat plate and runner push plate within the three-plate mold.

When in use, the set screw is screwed into the screw hole of the part to be fixed, and the end of the screw is pressed against the On the surface of another piece, even if the former piece is fixed to the latter piece. Slotted and hex socket set screws are used on parts where the nail head is not allowed to be exposed.

Compared with other bolts, hexagon socket head bolts are suitable for more assembly occasions, especially in narrow occasions, and are very convenient for assembly and maintenance. Because of its unique inner hexagonal structure, there are six force-bearing surfaces of the inner hexagonal bolt, which can effectively bear greater loads. Moreover, the hexagon socket head bolts can also be countersunk during use, which not only keeps the surface of the workpiece flat and beautiful, but also is not easy to be disassembled by others.
